为了适应广大SAP程序用户的需要,使模态综合技术在工程界发挥卓越的成效.我们从1983年开始以SAP5程序的动力分析部分功能为基础,加入固定界面法模态综合技术编制MSAP程序.这是一个具有绘图功能的固定界面法模态综合通用程序,规划引入SAP5程序的单元库、绘图功能、带宽优化等功能,同时增加了刚体模态的移频法求解,克服了SAP程序求自由悬浮子结构刚体模态上的困难. 去年完成的MSAP1程序只是总体计划的第一个版本,还只是一个具有绘图功能的空间框架双子结构模态综合通用程序.该程序允许划分子结构的数目是2,没有多重子结构功能,目前单元库还只配备了采用一致质量矩阵的空间梁单元,和能对每一个子结构单独进行
In order to adapt to the needs of the majority of SAP program users, the modal integration technology has achieved remarkable results in the engineering community. We have been developing the MSAP program based on the dynamic analysis function of the SAP5 program since 1983, and added the fixed interface method modal synthesis technology. This is a fixed-interface method modal synthesis general program with drawing function. It is planned to introduce the functions of cell library, drawing function, and bandwidth optimization of SAP5 program. At the same time, the method of shift-frequency method of rigid body mode is added to overcome the freedom of SAP program. Difficulty in the modal physics of suspended substructures. The MSAP1 program completed last year was only the first version of the overall plan. It was just a space frame dual substructure modal synthesis general program with drawing functions. The program allows the number of substructures to be divided into 2, there is no multiple sub-structure function, the current cell library is only equipped with a spatial beam element using a consistent mass matrix, and can be performed independently for each sub-structure
